GEORGE EDVARD COOKE, OF OLARKSVILLE, TENNESSEE.

SHINGLE--SAWING MACHINE.

Application man August 14, i835.

To all whom it may concern;

Beit known that I, GEORGE EDWARD COOKE, of Clarksville, in the county ofMontgomeryl and State of Tennessee, have invented a new and ImprovedShingle'Shaving Machine, of which the following is a full, clear, andexact description.

My invention relates to machines more particularly adapted for shavingrived shingles to a iinsh and with a correct taper from heel tov point,and adapted,also,for shaving staves and shaping pieces for wagons,agricultural implements, &c., and the object of the invenvention is topromote the effectiveness of machines of this character by providingsimple eiiicient means for preventing the shingles or pieces fromslipping under the action of the shaving-knife; also means fordischarging the shaved shingles or pieces from Athe machine, and forresetting the discharging devices, and all worked automatically by thereciprocating sash.

The invention consists in certain novel features ofconstructionandfcombinations of parts of the shaving-machine, all as hereinafterfully described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of referenceindicatecorresponding parts in all the figures.

pieces placed one on cach of the beds D D of the machine will be shavedto a proper taper or shape at each complete reciprocation or forward andback stroke of the sash, which will be .moved in the frame A by anyusual or approved mechanism, not necessary to show or describe.

The shingle-beds D are pivoted on pins d d to the frame A and inopenings of its top, so that the sash B slides over the beds, and thebeds are held up to support the shingles as the knives C act on them bymeans of heavy tappcts D', which are Vfixed to shafts D2, journaled inthe frame A.

On the shafts D2 are fixed the disk-wheels D3 D", cach of which isprovided with two pairs of pins, el d2 d d2, and also withdiamctrically-opposite peripheral stop-shoulders d cl.

To the frame A of the doubleacting machine is pivoted atb the lower endof a lever, B, which at its upper end has a pin-and-slot connection, asat b', with the sash B, so that as the sash is reciprocated, the lever Bwill be rocked. As seen best in Figs. 1 and 2, there are pivotedat theirinner ends on a pin, b2, in lever B', the inner ends of theindependently-acting bars B2 B,which extend opposite ways, so that thetwo hooks b3 b4, formed by notches cut in the lower edges of thebars,will successively engage the pins d d2 as the lever B is rocked togive intermittent half-revolutions to the shaft D2 and their tappets D',for raising the shingle-beds D and letting them fall at the propertimes, as hereinafter more fully explained.

To the levers B are pivoted at e the oppositely-extending bars i" Ewhichhave snp IOO port at their outer ends in slots of bracketplates E, xedto the frame A, and are provided, respectively,with the hooks or shoulders e which are adapted to lock against the lowermost shoulders, d3 ord*, of the disk-wheels D3 D4 to lock their shafts D? and tappets D'against forward movement,and simultaneously with the engagement of thesehook-bars E' E2 with the disk-wheels, as aforesaid, a pin or stud, d5,on the disk-wheel presses back a spring-pressed pin, e3, held to theframe A, and passes above said pin,which then springs out and prevents aback movement of the diskwheel, which thus held against rotation bothways to lock the corresponding tappet, D', in upright position tosupport the bed D above it against the downward pressure of the knife Cas'it shaves the shingle or piece held on the bed by the roller F.Springs E3 are attached at opposite ends to the opposite bars B`2 E' andB3 E2, and act to draw the bars B2 B3 into engagement with the pairs ofpins d' d2 on the disk-wheels D3 D4, and also to engage the shoulders e'e2 of hook-bars E' E2 with the peripheral shoulders d3 d* of thedisk-wheels.

There is a roller, F, mounted in verticallyspring.

movable bars f, fitted in brackets f' f', held to the sash B in front orin advance of each of the knives C, a platespring atf2 being pivoted tocarry the roller downward with a pressure which may be regulated by ascrew, f3, threaded through the top crossbar, f above the spring andswiveled to the center of the (See Fig. 7.) The roller F may be presseddownward by spiral springs fitted above the boxes F, if preferred.These'presserrollers F hold the shingles down to the beds D directly infront of the cutting-edges of the knives C, and yield as they advancetoward the higher ends of the beds D,which are held by the tappets D' ata proper incline to cause the knives to give a correct taper or shape tothe shingles or pieces. (See Figs. 3 and 4.) The presser-rollers thushold the shingles so that if warped or twisted when laid on the bed theywill be pressed iatas they are shaved, and when finished will have auniform thickness across their entire width at any place from heel topoint. The presser-rollers F also coact with the yielding plates orguards H in preventing the forward ends of the shingles from escapingfrom a thrust or end bearing should the shingles or pieces be warpedlengthwise,-`and as next explained. When theshinglebed D is held fullyup at its free or forward end by the tappets D', its face at saidforward end will lie a little below the top of a thrust-block, G, fixedto and across the top A' of the frame A, so that a shingle lying flat atits forward end on the bed D will be pressed by the knife C against theshoulder g of saidthrust-block during the entire operation of shavingthe shingle, but should the shingle or piece be curled upward when laidon the bed the forward end of the shingle or piece will bear against theguard H, as indicated in dotted lines in Fig. 3, said guard H beinginclined v are connected by a cross-bar, h2, at their back,

or outer ends. The side pieces, h'h', are fitted by tongues to rabbetsor grooves in the under. sides of guide-bars H' H', fixed to theframetop A', so that the guard H and its frame h h' 71? may slideforward and back on thetop A'. A spring, H2, is placed on a bar or rod,ha, fixed to guard Hand supported loosely in a post or bracket-piece,if, fixed to the frame-top,v the springbeing between. the guard and saidpost, so as to throw the guard toward the adjacent bed D, and until theinner ends of the said pieces h' strike the back edge of the thr'ustbarG. The inner ends of the pieces h' preferablyare extended at their lowerparts into under-cuts or notches in the vbar G, so as to moreeffectually resist the tendency of the guard H to rise by the pressureof the shingle or piece on it. At each side ofthe guardframe is pivotedati' a lever, I, which has a shoulder at z" adapted to look behind theframe when the guard H is pressedinto normal position bythe spring h,the lower face portion of the guard then being even with the edge orshoulder of the thrust-block G, against which the forward end oftheshingle or piece is pressed by the knife C.d A spring, I', connects theouter ends of the levers I I and draws their shoulders i' iu behind theguard-frame. rIhis locking action of the opposite levers I I on theframe of the guard prevents the guard from being forced forward by theupturned end ofa warped shingle or piece being shaved and which mayhappen to rest against it. When the sash B has advanced sufficiently tocause the roller F to press this end of the shingle down flat to the bedD, the shingle then will bear against the edge shoulder g of thethrust-bar G, and about at this time trip-blocks I2 I2, xed to oppositeside bars ofthe sash B,`will act on the inner ends, if, of the oppositelevers I I to disengage their shoulders i' from the guard-frame andpermit it to be forced back by the contact of the roller F with theguard H as the sash completes its stroke in that direction to carry theknife C clear through the shingle or piece, and as shown at theleft-hand end of Figs. 1, 2, and 3. As the rollerFrecedes on thereturnfstroke of the sash B, thevspring Hz will force the guard H backto its normal position, and the spring I' will set the shoulders t" oflevers I again behind the guard-frame, ready for the' next stroke of thesash toward the guard. It will be seen that the guard H, with the rollerF,fornns an effective means to prevent forward slip of the shingle orpiece from the thrustbar G on the frame; hence the action of theshaving-knife C on every shingle or piece will IOO lIO

be positive, andthe shingles or pieces will not stick to the knife andclog the machine. The knife-bed D has inclined rabbets d d at oppositesides, which allow the trip-blocks I2 to pass along the bed on their wayto the levers 1,(see Figs. 2 and 8,) and the opposite side bars of thesash B are or may be connected by arching erossbars or bridge-pieces Bt,which may move over the guard H and its connec tions as the sash Breciproeates After the shingle or piece. has lbeen shaved the bed D isallowed to swing down on its pivots (ZT by the turning of the tappet D',which had supported it, and, as 'shown at the left-hand side of Fig. et,and just asthe bed drops the shaved shingle or piece is automaticallydischarged from the machine by devices next described.

Across the machine, and about under the pivots CZ of the `shingle-bed D,is journaled a shaft, K, to which are fixed the shingle-dischargingiingers k k, which project through or are adapted to slot-s ZS (Z8 inthe bed D and coinciding slots d fZ in the top A' of frame A. About at aright angle to the fingers kk is fixed to the shaft K an arnnt', whichis adapted to be set over a spring-pressed trip-pin, L, fitted to slidelaterally in the machine-frame. To the shaft K also is fixed the bentarm It, against the hooked extremity of which the bent end m of apnslrrod, M, is adapted to act for setting the arm It' over the trippinL, and thereby forcing the fingers k 7c back into the slots d" d of theframe A, as shown in Figs. 2 and 3, or, in other words, set-ting thesengers in position ready to deliver a blow on the back end of the shavedshingle or piece to discharge it from the machine, the force of whichblow is determined by the tension of a spring, N, which is coiled aroundthe shaft K and fixed at one end to the bent arm m, and at the other endto the frame A or its top A'. The spring N thus is the prime mover ot'the discharging iingers. The push-rod M is supported so as to slide in asuitable guide-eye, m', on the frame, and at its forward end isconnected to a bolt end, m2, which is threaded into the bent end o of abar, 0, and receives a. nut, in", outside said end o of the bar, whichprovides for lengthwise adjustment. The other end of the bar O ispivoted to the lower end of a lever, P, which is pivoted atpto themachine-frame, and a spring, Q, attached to lever P and the frame Adraws theY lever and the push-rod M back after they have been forcedforward to set the arm ZZ" over the trip-pin L and out ofthe way of thearm k2 ofthe shaft K as it il'ies back when the discharginglngers k arereleased by withdrawal of the trip'pin L from beneath the arm 7c', ashereinafter explained. An arm or pin, J, fixed to the sash B is adaptedto strike the top of the lever P on the return-stroke of theshaving-knife C, to force the rod M endwise against the arm 7c on shaftK for setting the arm k' over the trip-pin L. As best seen in Figs. 9,l0, and l1, the trip-pin L is fitted loosely in the frame A and in abridge piece or bracket, L', fixed to the frame, and on the pin L isfixed a disk or plate, L2, in which is fixed a pin, Z, which acts by itsinner end against the face of the teeth i' of' a circular rack, R, whichis fixed to a ratchet-wheel, R', which is placed loosely on the piln L,and has peripheral teeth r', which are engaged by a pin, s, in one endof a connecting-rod, S, which is pivoted at its other end to a lever, T,which is pivoted at t to the frame A, and has at its upper end a slot,Z', so arranged that a pin, U, on the sash B may enter the slot forthrowing the lever 'li forward and back for actuating the rod S toimpart motion to the ratchet-wheel Rin the direction of arrow l, andthereby causing each tooth r of rack It to thrust out the pin Z, andconsequently the trip-piu L, to withdraw its inner end, Z', `from thearm 7i" of shaft Kto allow the spring N to throw the fingersc forward todis charge the shaved shingle or piece. The pin Z projects also from theouter face of the plate Ll and enters a hole in the bracket L', so as toprevent the trip-pin L from turning axially in its bearings, and thusholding the beveled portion of its inner end, Z', downward, so that thearm k' of shaft K will strike said beveled part of pin L and force thepin outward to allow the arm to lodge on top of it to hold the fingers7c set back when and after the puslrrod M has acted on the arm k2 of theshaft, as hereinbefore explained. A spring,V, held to the tri p` pin L,or it may be to the bracket L', acts between the plate LZ and thebracket to force the trip-pin L back into position for engaging orsupporting the arm 7i" ot' shaft K, and a spring, V', held to the frameA at one end acts by its other end against stop-pins r2 set in the innerface of ratel1et-\vheelRto prevent back move ment of the ratchet.

At V is shown a rigid arm or plate, which is fixed at one end to theframe A, and at its other end carries a pair of pins, w w, which standone at each side of the connecting-rod S to guide it so its pin s actsproperly on the ratchetwheel R, and a spring, V2, is fixed at one end tosaid arm XV, and acts by its free end to hold the rod S up to cause itspin s to engage the ratchet-wheel.

The arrangement of operating-levers of the singleaeting machine differssomewhat from that shown in the double-acting machine. By referring toFig. 9 it will be seen that the main lever B', which is connected to thesash B, is pivoted at b a little below its center to the frame A, and'its lower end is connected by a rod, B, with the lower end of a lever,B, which is pivoted at b to the frame A, and the lockbar E' and lever B2are pivoted to the le ver l above its pivot b to give the requiredmovement to said lever and lock-bar in open ating the tappet-shaft Dl tolower the shinglebed D and raise and lock it, as hereinbefore explained.

I will now describe the continuous operation with more special referenceto the single-act- IOO ing machine,as follows: In the positions of theparts shown in Fig. 9 the sash B is quite at the extreme limit of theback-stroke, and the pin or arm J is acting on lever P to force rod Mforward to set the arm 7c ou shaft K over the trip-pin L and throw thelingers 7c back onto the pin L, and the outer hook or notch, b", of barB2 has just drawn the wheel D around in direction of arrow 2 to moveshaft D2 for lifting the shinglebed D to its highest position by thetappct D', at which time the shoulder e of bar E had met thel shoulderd" of wheel D, and one stop, d5, on said wheel hadlodged on the springstop-pin e3 todoublelock the tappet, so it firmly supports the bed `D,as hereinbefore described, and the pin U on the sash had passed by thelever T after having moved it to the position shown for tripping thefingers sinto action for discharging the last shaved shingle or piece..The next shingle or piece to be shaved now is laid on the bed D with itsforward end abutting the thrust-block G or guard H, and as the sash Bmoves forward in direction of arrow 3 to carry the knife C through theshingle or piece the pin J will leave the leverP and al. low the springQ to drawback the rod M from the arm k2 ol' shaft K, and the lever BGwill throw thebarB2 forward, so thatits inner notch engages the oppositepin, d', on wheel D, ready for the next return or back strokeof thesash, and the shoulder e of bar E will be moved forward away from theshoulder d* of wheel D to allow the wheel to be turned in direction ofarrow 2 at the proper time. As the knife C passes through the shingle orpiece, the roller F and guard H coact, while the guard is pushedforward, as hereinbefore fully described, to prevent slip of the shingleor piece, and the pin U engages the slot t of lever T to rock the leverand throw back the rod S and set its pin or tooth s into the next notchor tooth, i", of the ratchet-wheel R', and after the knife C hascompleted its cut through the shingle and the motion of the shaft isreversed the guard H will follow the roller F backward to the edge ofthe thrust-block G, and the bar B`Z will draw on the pins ddisuecessively by its notches b b" to turn the wheel D3 in direction ofarrow 2, and thereby turn the tappets D, to allow the shingle-bed D tofall, as at the lcft-hand end of Fig. 4, and during this fallingmovement of the bed the pin U on sash B will again engage the lever T,to throw its upper end backward to the position shown in Fig. 9, andthereby carry the rod S forward to turn the ratchet-wheel B in directionof arrow l the distance of one ot' its teeth i" and 1', and therebyforce the trip-pin L outward, to withdraw it from the arm la of shaft Kand allow the spring N to throw the fingers c backward and strike theback end of the shaved shingle or piece lying on the lower bed, D, anddischarge it from the machine, as indicated at X in dotted lines in Fig.4. As

the back-stroke of the sash B is about half completed, the tappet D willagain begin to assume an upright position with its other end upward, andas it fully raises the 'shingle-bed D the wheel D3 will again be doublylocked by the stops e di and shoulders d e', to hold the bed D in place,and as the sash completes its .back-stroke the pin J on it will againpush back the lever P to thrust the rod M forward against the arm k2 ofshaft K for setting the arm 7c over the trip-pin L, and all is ready forthe next forward `stroke of the sash to shave the next shingle or piecelaid on the bed D.

In the double-acting machine shown, the one trip-pin J on sash B acts onboth the settinglevers P P of the discharging-fingers 7c at opposite-ends of the machine, and the sash has a pin, U, at or near each end,which, at the extremes of the strokes of the sash each way act on thelevers T to trip the shingle-discharging fingers k into action at eachend of the machine as the beds D fall when their respective tappets Dare turned to horizontal positions, it being understood that onelshingle or piece is being shaved at one end ofthe machine while anothershingle or piece is being discharged at the other end of the machine, ashingle or piece being shaved and discharged at each hal f-stroke of thesash. The one lever B aetuates the opposite pairs of bars B2 E B3 Ewithlike effect on the disk-wheels D3 D4 and their respective tappets, ashereinbefore described for the single-acting machine, and, if desired,the lever B may be extended upward at one end of the double-'actingmachine to connect with the sash, as shown in the singleacting machine,Fig. 9, and in which case the lcverB in Fig. l will not be connectedwith the sash, as therein shown,and the second pair of operating-bars,E2 B3, will be connected between their operating-lever and the lever B',which connects with the end of the sash, as will readily be understood.

It will be seen that all the operations ofthe machine are automatic andpositive, and that the working capacity of the machine is limited onlyby the expertncss of the attendants who feed the rived shingles orpieces to it.

A spring pressed or yielding bar may be mounted across the sash B as asubstitute for and mechanical equivalent of the roller F; but

-the roller is preferred, as it will operate to hold the shingles to thebed D with less friction than would the bar. It is evident that two ormore of the tappets Df may be fixed to the shaft D2 under each of theshingle-beds D to support the beds, and the setting and trippingmechanism of the discharging-lingers 7c maybe arranged for one bed D ofthe-double-acting machine at .one side of the machine-frame and for theother bed D at the other side of the frame, and the trip-pins on thesash will be correspondingly arranged to throw the levers P to trip thedischargingfingers, substantially as above described, and the frame ofthe double-acting machine may IIS ISO

be lengthened, so that the ends of the sash will not run past the endsof the frame, as in Figs. 1 and 5, when the machine is operated.

As before stated, the maehineis adapted not only for shaving shingles,but is adapted also for shaving staves and for shaping pieces for use inbuilding wagons, agricultural implements, and in other work.

It is obvious that the mechanism for setting the arm k of the shaft Kover the trip-pin L, and for tripping the arm from said pin may vai-yinits details from that herein shown and described, as other means may bedevised for securing these results by or from the action of thereciprocating sash.
